Not a direct answer for your question (I don't remember how
send/finish works), but I think that this approach is not robust in
any case (sending stuff to the client might hang, and then the Scheme
thread will die with an exception). A better approach would be to
generate GIFs in some directory using random names, and have a
seperate thread that periodically scans it and removes files that are
older than some threshold.
